BINDING DEVICE FOR LOOSE-LEAF BOOKS.

Application led April 8, 1912.

To all 107mm @'15 may concern Be it known that I, JOHN GninsiNcnR, asubject of the Emperor of Germany, residing in the city of Los Angeles,State of Califoruia, have invented a new and useful Binding Device forLoose-Leaf Books, (Case No. 3,) of which the following is aspecification.

rlhis invention relates to an improved leafretaining clip, an object ofthe invention being to provide such a clip adapted to hold a smallleaf-section or bunch of leaves and also adapted for extension orexpansion to retain a relatively large leaf-section.

This binding device is particularly adapted for holding a series ofmagazines together in bound volumes. rlhe clips and other parts of thebinder will be sold to the user who can then bind his own periodicals inconvenient form for reference. When the individual leaf sections consistof sepa rately bound magazines, all the leaves thereof will be securelyheld by the teeth of the retaining clips, even though said teethpenetrate only the outer leaves of each section.

rlhe leaf clip hereinafter described and claimed is capable o-f a verywide range of adjustment and maybe detachably secured to a very fewleaves or to a leaf-section including a large number of leaves.

This invention, therefore, relates further to a new article ofmanufacture consisting of a fastening clip for loose leaf books, saidclip having teeth adapted to grip the leafsect-ions to which it isattached, and said clip being adapted for engagement with fasteningmeans to hold the same in the operative position.

Referring to the accompanying drawings, which illustrate the invention,Figure 1 is a plan view of an open book provided with this improvedclip; Fig. 2 is a section on line @c2-m2 of Fig. 1; Fig. 3 is a sideview of the clip; Fig. l is a face view of said clip; Fig. 5 is a backview thereof; Fig. 6 is an end view thereof, the extensible feature ofthe clip being indicated by dotted lines.

Referring in detail to the drawings, the bock illustrated comprises theusual sides 1 united by the flexible back 2 and having the independentleaf sections 3. Said leaf sections may consist of a large or smallnumber of leaves and the leaves may be independent of each other if fewin number and may be larger in number if bound into magazines orSpecication of Letters Patent.

| the like. To each of said leaf-sections is atltached an apertured clip4;, the preferred construction of which is illustrated in detail inFigs. 3 to G. Each of said clips consists of a plate approximatelyU-shaped in general outline. Said clip comprises the arms or side plates5 united by a plurality of bendable curved strips 6 which may be eX-tended to widen the clip as indicated by dotted lines in Fig. G. Eachside plate 5 is provided with a plurality of inwardly directed teeth 7to grip the edge portions of the leaf-sections 3 as shown in Fig. 2.Each side plate 5 is also provided with a slot 8 to receive theretaining straps 9. Said slot 8 is preferably furnished with anextension l1 to receive a binding-post (not shown) if the book isprovided with posts instead of the straps 9.

The strap-retaining fiaps 1Q are releasably held down by the heads ofstuds 13, eyelets t carried by said iiaps, cooperating with said studs.

In operation, two of the fastening clips 4L are secured to the back edgeof each leafsection or magazine number to be bound into the volume, theside plates 5 being hammered down to drive the gripping teeth 7 into theouter leaves of each leaf-section. Then the various leaf sections areplaced in order and the binding straps 9 are led through the apertures 8of the clips in a well known manner.

I claim:

1. In a loose-leaf book, a plurality of independent leaf sections, aretaining clip for each of said leaf sections, said clips each having agripping portion, said clips having apertures to receive means forholding them in the operative position, each of said apertures having anextension adapting the clip to receive a rod of greater diameter thanthe other portion of said aperture, and means to hold said clips in theoperative position.

2. In a loose-leaf book, in combination, loose-leaf sections, and aplurality of retaining clips for said sections, each of said clipshaving a slot extending therethrough to receive fastening means, each ofsaid slots having a lateral extension to adapt the aperture to receive arod of greater diameter than the slot portion of the aperture, andfastening means for the clips.

8. As a new article of manufacture, a fastening clip for loose-leafbooks approxi mately U-shaped in general outline, the base portion ofthe U consisting of a pair of relatively narrow bendable strips ofmet-al normally curved toward the mouth of the U and which are adaptedto be straightened out to widen the clip, and grip-teeth projecting fromthe end portion of the clip.

4. As a new article of manufacture, a fastening clip for loose-leafbooks consisting of a body U-shaped in cross section, each arm of said Uhaving teeth which are clirectecl toward the teeth of the other arm,there being an aperture through said clip to receive a fastening strap,said aperture having an extension adapting the same to receive a rod.

5. As a new article of manufacture, a fastening clip for loose-leafbooks consisting of a U-shaped clip having a normally inbent extensibleportion uniting the arms of the U.

6. As a new article of manufacture, a fastening clip for loose-leafbooks consisting of a U-shaped clip having a pl'lrality of extensiblenormally inbent strips uniting the arms of the U.

In testimony whereof I have .ereunto signed my name in the presence oftwo subscribing witnesses at Los Angeles, in the county of Los Angelesand State of California, this 30th day of March, 1912.
